Answer 1

Answer:

4pi millimeters.

Assuming pi = 3.14159, we can approximate the diameter to be 12.56636mm

Step-by-step explanation:

To get the circumference of a circle, just multiply the diameter by pi

Answer 2

Answer:

C=0.125m

Step-by-step explanation:

C = 2[tex]\pi[/tex]r= (2r)[tex]\pi[/tex] = d[tex]\pi[/tex] = 0.004·[tex]\pi[/tex] = 0.125m

The common factor is x, so factor out the x.

3x + 4x = x(3 + 4)

-Entire triangle region : 120 sq.cm

-Area of semi circle : 100.53 sq.cm

-Entire composite figure : 220.53 sq.cm

Step-by-step explanation:

Area of triangle = ½ × base × height

= ½ × (8+8) × 15

=½ × 16 × 15

= 120 sq.cm

[tex]area \: of \: semi \: circle = \frac{1}{2} \pi {r}^{2} \\ = \frac{1}{2} \times \pi \times {8}^{2} \\ = \frac{1}{2} \times \pi \times 64 \\ = 32\pi[/tex]

=100.530.......

=100.53 sq.cm (rounded to 2 decimal place)

Area of entire figure = 120 + 100.5353

= 220.53 sq.cm

-hopes this helps<3

Step-by-step explanation:

need help with logs problem pls asap i’ll mark u brainlist

Answers

You must use this formula: A= P(1+r) power of t
P=starting price
r= rate in decimal form
t= number of years

Since you own the jersey for 1025, that will be P.
The rate is 14% or 0.14.
The number of years is calculated by subtracted 2028 and 2022 (today’s date), which is 6.
A=1025(1.14) power of 6. Plug that in a calculator and you have your answer. You may need to round to the nearest hundredth, the question does not specify.

A computer store changed the price of a laptop. It was originally $900, but now it is $1,100.Find the percent of change

Answers

Answer:

The percent of change is 22.22%.

Step-by-step explanation:

You can calculate the percent of change by subtracting the original number from the final number and dividing that by the original number. Then, you have to multiply the result for 100:

percent of change=((1,100-900)/900)*100

percent of change=(200/900)*100

percent of change=22.22%

According to this, the answer is that the percent of change is 22.22%.

Answers

Answer:

Step-by-step explanation:

I hope you want the area.

Area = L * W

L = 24x^3

W = 5x^2

Area = 24x^3 * 5x^2

Area = 120 * x^(3 + 2)

Area = 120 * x^5

Note

When you multiply numbers or letters that have powers, if the base for both of them is the same, the powers are added.

The above answer is an example x^2 * x ^3 are letters (x) that are raised to the 2nd power and the 3rd power. You add the powers.

Numbers can do the same thing

Answers

Answer:

I think it B but I really don't know cause need like an example

The k in the equation represents Option B) The constant of variation

What is a constant in an equation?

A constant is a value or number that never changes in expression; it's constantly the same. For example,  36 and 82 are constant because its face value is 36 and 82 respectively. Its value never changes.

Given here the equation y=kx where k is the slope and a scalar value thus it is independent of x and y and thus is a constant.

Hence, The k in the equation represents Option B) The constant of variation

Step-by-step explanation:

Well theres not exactly a formula, I jsut solve the 3 faces and then double it all since 2 are the same for each except for 1 so the first side is the 10X12 one. that would give you 60 and then you double that and get 120 since 2 same faces.

The next one the 6X13  one is just a sideways rectangle, a=lw and that would be 78. Two faces same side double 78 and get 156.

Now the final side is the bottom which is jsut 10X6. a=lw and that would eqaul 60. No need to double since thats the only side that doesn’t have a duplicate. Add all your result up and you would get
